Numerous types of penetrators exist. Tungsten is often a material of choice in the penetrator art. A typical method for fabricating penetrators from tungsten involves the use of tungsten powder metal, which is a heterogeneous mixture of tungsten and other metal powders. The mixture of powders is compacted into the desirable shape, liquid phase sintered and processed into penetrators.

The benefit of using tungsten as the material is that the extremely high melting point of tungsten (approximately 3410° C.) makes it impracticable to sinter the tungsten whiskers together to form a structurally sound penetrator without coating them with a lower melting point coating. For example, in prior art tungsten penetrators have been made by liquid phase sintering polycrystalline tungsten powder, each particle of which has been coated with a lower melting point coating such as iron/nickel in the ratio of 7 iron/3 nickel by weight in a hydrogen atmosphere at a temperature of 1475° C. for approximately one hour. The resulting penetrator body consisted of 90% tungsten, 7% iron and 3% nickel by weight.
